DISTRIBUTER EvIEGHANISM FOR TYPOGRAPHICAL MACHINES.

APPLICAI'KON FILED MAY 10.1911.

Patented N (W. 17, 1914 e fixed stud i, the said support then engaging under a plate 6 festto the lever arm (3, .all as shown in Fig. 2. I

f has rotatable on it a roller g which is in constant contact with theside oi a toothed wheel 71- fast (in the spindle of the distribu ter screw 0:. 'Byuneans of an adjustable, screw or abutment 2' the lever f can be adjusted so that the shoulder a (Fig. 3) of the distributor screw a will not be pressed against the frame ,l; by the spring Z v:hic h retains the said lever f in its normal position.

Under normal conditions the matrices 1 will be distributed freely into the magazine entrance. Should however a magazine channel become blocked and a matrix thereby be caused to project above the magazine entrance, as shown in Fig. 3, the next matrix moved along by the distributor screws, strikes against the said projecting matrix and is stopped byiit. .z-is the distributor screw a continuesto' turn, it acts upon this stopped matrix as it would upon a fixed ebumnent or not and thereby screws itself in a leftward direction out of its normal 36$ltl0X-:,ll1itt is to say, in the direction opposite to that in which the matrices are propelled by the distributor screws. bus the pur wheel it rocks the lever f, y, from the position in which it is shown'in Fig. 2, to that in which it is shown in Fig. 3, so that the arm f of the said lever, releases the plate 6 of the stop lever 15, which latter under the action of a spring 2 swings back to bring its pin qyintotlie path of the pin 9" and thereby effect thestoppage of the disk 0 and (listributer screws and allow the pulley cto continue its rotation independently of the said disk and screws.

The stoppage of the distributor mechanism is also eilected by the before described devil, when, as sboWn-in Fig. 5, a matrix sticks in the distributer lift box, owing say to failure of the matrix lifter n to raise the the said matrix sufficiently for its top lugs to clear the usual stop shoulder 37 on the guide rail 0. In. such a case the partly raised matrix would be arrested by the said shoulder p, and would engage with the distributor screw a, which would thereby, as before described, be displaced longitucli-, nally, and effect stoppage of the distributor mechanism.

The strength of the spring Z isfsuch as to enable it to retain the screw a in its normal position under ordinary working conditions, and to yield when, as aforesaid, the said screw is moved longitudinally through engagement with a blocked matrix.

13y reason of the foregoing arrangement the magazine entrance can be made simpler 1,: meet and stronger than heretofore, as the partitron plates can be securedat both edges.

A a Having described my invention I declare The upper arm of the releasing lever 71,,

that what I claim and desire to secure by Letters Patent is l. Iii mechanism for distributing matrices in typographical machines, the combination 0' a rotatable screw by which the matrices a e propelled, supports for the said screw in which the latter is capable of moving axially,'rotating' means for the screw, comprising intermeshing gear wheel's, one fast on the shaft of that screw and axially movable with it, and another one fast on a second'shaft, a driving pulley loose on the second shaft, a disk fast on this shaft and capable of being rotated by friction by the driving pulley, a stop leve normally. retained out of engagement Wit the disk, and a releasing lever normally engaging with the stop lever to hold it out of engagement with the disk, the said releasing lever being actuated by the axial movement of the geer- Wheel so as to free the stop lever and permit it to engage the disk.

2;. In mechanism for distributing matrices in typographical machines, the combination of a rotatable screw by which the matricesare propelled, supports for the said screw in which the latter is capable of'moving axially, rotating means for the screw, comprising intermeshing gear Wheels, one fast on the shaft of that screw and axially mov able with it, and another one fast on a secondsha'ft, a driving pulley loose on tbesecond shaft, a disk fast on this shaft and capable of being rotated by friction by the driving pulley, a stop lever normally retained by a releasing lever out of engagement with theclisk, the said releasing lever, plateson' one end of the stop lever and on the releasing lever respectively, normally engaged with each other to hold the releasing lever out of engagement with the disk, the other end of the releasing lever being held by aspring in operative contact with the axially movable gear wheel, and the said spring.

In mechanism for distributing matrices in typographical machines, the combination of a movable distributor member, and stopping means operated by the movement of said member, the said stopping means comprising two independently mounted levers, one of which is actuated by the movement of the said member'and acts upon the other to effect the stoppage of the distributing mechanism.

In witness whereof I have hereunto set my band in the presence of two witnesses.
